Answer:
x=-1+[tex]\frac{1}{4}[/tex][tex]\sqrt{130\\}[/tex] or x=-1+[tex]\frac{-1}{4}[/tex][tex]\sqrt{130}[/tex]
Step by step:
Step 1: Subtract -5 from both sides.
8x2+16x−62−(−5)=−5−(−5)
8x2+16x−57=0
For this equation: a=8, b=16, c=-57
8x2+16x+−57=0
(plus-minus) = ±
Step 2: Use quadratic formula with a=8, b=16, c=-57.
x=[tex]\frac{-b(plus-minus)\sqrt{x} b^2-4ac}{2a}[/tex]
x=[tex]\frac{-(16)(plus-minus)\sqrt{(16)^2-4(8)(-57)} }{2(8)}[/tex]
x=[tex]\frac{-16(plus-minus) \sqrt{2080} }{16}[/tex]
ANSWER:
x=-1+[tex]\frac{1}{4}[/tex][tex]\sqrt{130}[/tex] or x=-1+[tex]\frac{-1}{4}[/tex][tex]\sqrt{130}[/tex]
15. Asher weighs 15 pounds less than three times the weight of Audrey, his sister. Asher
weighs 27 pounds. Write an equation that can be used to find w, the weight of Audrey. Then,
solve the equation
Equation:
Solution:
Answer:
15x-y=27
Step-by-step explanation:
I think if im wrong my apologies haven't done that in a bit
The weight of Audrey will be 14 pounds based on the given equation formation.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Suppose the weight of Asher is x then according to the given question,
x = 3w - 15
And, x = 27
27 = 3w - 15
3w = 42
w = 14 pounds
Hence "Weight of Audrey will be 14 pounds based on the given equation formation".

SOMEONE PLEASE HELP AND EXPLAIN HOW TO DO THIS!!
Answer:
Your answer should be B or D.
Step-by-step explanation:
You have to find x. If the first side is 60 degrees and the other is 70 degrees, that means that the last side should be similar to that. yo can use a protractor if you have one, or you can estimate. now for the equation part. once you have the degree for the angle, you need to use the numbers to multiply to get the number. Multiply 8 by all of the numbers. Since the angle is acute, the answer has to be less than 90.
